I have a feature that has three User Stories. All User Stories have been accepted, however, the feature still says it is 67% completed with only 2 of the 3 stories and story points accepted. These User Stories were moved to accepted using a Kanban board.
After determining which story is not being listed as Accepted in the feature, use the Kanban board to move the User Story from the "Accepted" column back to a column earlier in the process. Wait an hour THEN move the User Story back to the "Accepted" column.
***This next part was not validated, but I would recommend trying this if the above doesn't work.
Change the schedule state of the User Story directly in the User Story instead of the Kanban board.
